Thank you Matt, (01)
This is an intriguing idea to me, that the number of individuals that
have a particular structure is the defining characteristic of when to
use a database or a knowledge base. (02)
Do you think that because a knowledge base is mostly a collection of
singletons, that effectively using a knowledge base predisposes one to
want to use logic, rules, and categories to describe it? (03)
